I did a DIY candy bar. I sourced all my bowls from charity shops, Wilkinsons and friends. E.g the sunday glasses with the love hearts and Mr & Mrs candy in were 6 for 99p!! bargain. The bags (UK seller), tongs and scoops i bought off ebay, they were 99p (£1.99 for 100 bags) each from Hong Kong or China (free delivery). I managed to get the LOVE bowls off a friend who lent them to me as they cost £20+ which i was not happy to pay.
Sweetie wise i went to Makro as they had a bigger selection than other places e.g Costco. I spent £50 (inc VAT) on the sweets from there, i didnt go for brand name sweets (Haribo) as the Makro own, cant remember the name, were a) taste just the same, b) lower in price and c) got more in a box. I bought way too much but id rather that than to little, just meant i ate sweets for tea for a week. I had 126 guests and bought 12 boxes - 3 didnt even make it out my house and i had sweets left over from the night.
I also bought love hearts and Mr & Mrs rock from ebay. 100 love hearts were £4.99 (inc delivery) and the Mr & Mrs were £3.49 for 50 (inc delivery). I also bought sweeties off an ebay seller as i bought 3 (2 for the table and 1 as a gift) she did me a deal. It worked out at £12 a tree inc delivery.
